1Claim. 1

This invention relates to an air circulating system for buildings and it is one object of the invention to provide a building construction wherein a base board or chair board of a wall is formed with openings, or air passages, through which cold air near a floor may pass into a wall from which the air flows under the floor of a room to a pipe leading to a furnace where the air is heated and returned to the room through a register or grating set into the wall near the tops thereof or at any height above the floor which will be suificient to assure a good circulation of air through the room.

Another object of the invention is to provide a building construction wherein spaces between the vertical studdings of a wall which are closed by plaster boards or facing sheets constitute passages with which the gratings and the openings in the chair boards communicate, thus allowing a Wall which divides one room from another to serve as conduits for the two rooms.

Another object of the invention is to provide a structure of the character which is simple in construction and not liable to be clogged or otherwise rendered inoperative.

The invention is illustrated in the accompanying drawings wherein:

Fig. l is a perspective view showing a corner portion-of a room of a building having the improved construction.

Fig. 2 is a sectional view upon an enlarged scale taken vertically through one of the base boards of a wall.

Fig. 3 is a perspective view looking at the inner face of the base board.

Fig. 4 is a sectional view taken vertically through the lower portion of a wall and adjoining portions of a floor.

In Figure 1 there has been shown a portion of a building having the improved air circulating system incorporated therein. This building I has a base 2 formed of concrete, it being understood that the concrete slab 2 may represent a floor or ceiling of a building formed of poured concrete and having two or more stories. Furring strips 3 rest upon the base or slab 2 and upon these furring strips rest cross strips 4, the boards forming the wooden floor 5 being nailed to the cross I strips 4.

lower edges spaced upwardly from the base bar and the adjoining cross strips 4. It will thus be seen that the floor has space under it from the bottom of which extends a duct 9' through which air may be drawn back to an air furnace or to an air purifying and chilling apparatus by the usual fan with which they are equipped, the walls also being provided with spaces between the studdings l which have their lower ends in communication with the space under the wooden floor 5. A suitable number of ducts I0 are mounted in the spaces between the studdings and communicate with registers l I through which hot air from the furnace or cold air from the air conditioner is forced into a room from the furnace or the air conditioner.

The air which enters the rooms must be returned to the furnace or conditioning apparatus and in order to do so the air must flow into the space under the wooden floor 5. Therefore there have been provided air passages consisting of slots l2 communicating with recesses l3 formed in the rear faces of base boards or chair boards M which are nailed to the studdings and have their lower'edges resting upon the floor 5 and their upper edges formed with longitudinally extending recesses [5 into which fit the lower edge portions of the wall boards 9. The recesses l3 register with the spaces between the studdings 1 and as the floor 5 and the cross strips 4 are spaced slightly from the studdings and the base bars or rails 8 air flowing from a room through the slots l2 may flow downwardly through the spaces between the studdings and enter the space under the wooden flooring. This air finally reaches the return duct 9' through which it flows to the furnace or air conditioner. It will thus be seen that the air may circulate through the room in a very efiicient manner.

Having thus described the invention, what is claimed is:

In a building construction, a floor laid upon cross strips mounted across furring strips to prov1de space under the floor having an air return duct leading therefrom, a wall including a base rail extending across ends of the furring strips and vertical studdings resting upon the base rail in spaced relation to a confronting side face of an adjoining cross strip, said studdings being an air supply duct extending vertically in the wall between certain of said studdings and communicating with a register mounted through the facing sheet, and a base board for the wall mounted against lower portions of the studdings between the floor and the lower edge of the facing sheet and having a groove along its upper edge into which the lower edge portion of the facing sheet fits, said base board having its rear face formed with: spaced recesses located between the 10 studdings and open at their lower ends, the base board being also formed with longitudinally extending slots forming air passages leading from I the front face of the floor board and communieating with upper ends of the recesses.
